摘要：

A new coordination compound of Eu(III) with 1-methyl-1,10-phenanthroline-2(1H)-one (L) as a ligand has been synthesized and characterized using infrared spectroscopy, elemental analysis and single crystal X-ray diffraction. The structure contains isolated [Eu(L)(3)(NO3)(3)] molecules interacting through extensive it-stacking. Photoluminescence studies demonstrate that the complex shows line-like emission characteristic of Eu(III) when excited in the ligand-centered absorption bands, with a quantum yield of 22% and a lifetime of 0.74 ms.
